This page of Adsense
keyword information is intended to show you why certain keywords are so
valuable. The prices shown are the average of what people/companies have
paid for each click for that keyword. For instance, a company pays $10
per click to have their text link shown on websites about "foreign
monetary exchanges". When a visitor goes to that site and clicks
on the companies text link, the company pays Google $10. Google then pays
a portion of that to the website owner who is running Adsense ads on their
site. The portion Google pays is unknown.

I do not guarantee you
will make any money if you make websites about any of the keywords I talk
about on this site. In fact, for many of the keywords, you will find I
advise against making sites centering around that keyword. This may be
due to stiff competition, or maybe the market value of that keyword is
just too low, and the money will run out soon.
